Elastic supporting member for shadow mask frame

Abstract

The present elastic supporting member for use in a shadow mask frame has a fixing plate attached to the shadow mask frame; a supporting plate suspended from a conventional stud pin; a spring member interposed between the fixing plate and supporting plate; a pin by which a bracket of the fixing plate and the bracket of the supporting plate are hinged on each other; and stoppers to define the disposing distance between the fixing and supporting plates.

What is claimed is: 
     
       1. A shadow mask frame, face plate and elastic supporting member assembly comprising: a fixing plate attached to the shadow mask frame;   a supporting plate suspended from a stud pin of the face plate;   a pin by which a bracket of the fixing plate and a bracket of the supporting plate are hinged on each other;   a spring member interposed between the fixing plate and the supporting plate for urging the supporting plate away from the fixing plate; and   means for limiting a distance between the fixing plate and the supporting plate urged relatively away from each other by the spring member.   
     
     
       2. The assembly as claimed in claim 1, wherein the spring member is a coil spring. 
     
     
       3. The assembly as claimed in claim 1, wherein the supporting plate is made of bimetal. 
     
     
       4. The assembly as claimed in claim 1, wherein the fixing and supporting plates each further comprise a pair of flanges disposed in opposing locations for contacting each other to provide support for the supporting plate against twisting. 
     
     
       5. The assembly as claimed in claim 1, wherein the supporting plate has a guide of fork shape. 
     
     
       6. The assembly as claimed in claim 1, wherein the fixing plate and the supporting plate have a plurality of pins for determining a position of the spring member.
